waves

Question 1

wave

Answer 1

a disturbance in a medium that carries energy without a net movement of particles

Question 2

mediuma substance that can transmit energy

Question 3

transverse wave

Answer 3

a transverse wave is a wave that oscillates perpendicularly to the direction of the wave’s advance

Question 4

compressional wave

Answer 4

Longitudinal waves are waves which oscillate in the direction which is parallel to the direction in which the wave travels and displacement of the medium is in the same direction of the wave propagation

Question 5

sound wave

Answer 5

the pattern of disturbance caused by the movement of energy traveling through a medium as it propagates away from the source of the sound.

Question 6

water wave

Answer 6

surface waves, a mixture of longitudinal and transverse waves

Question 7

seismic wave

Answer 7

a mechanical wave of energy that travels through the Earth, typically generated by events like earthquakes, volcanic eruptions, or large landslides

Question 8

crests

Answer 8

a point on a surface wave where the displacement of the medium is at a maximum

Question 8

troughs

Answer 8

a long depression less steep than a trench

Question 9

rarefaction

Answer 9

the reduction of an item’s density, the opposite of compression

Question 10

wavelength

Answer 10

wavelength or spatial period of a wave or periodic function is the distance over which the wave’s shape repeats

Question 11

frequency

Answer 11

the number of occurrences of a repeating event per unit of time

Question 12

amplitude

Answer 12

the maximum displacement of a wave from its resting position

Question 12

refractions

Answer 12

refraction is the redirection of a wave as it passes from one medium to another

Question 13

diffractions

Answer 13

the deviation of waves from straight-line propagation without any change in their energy due to an obstacle or through an aperture

Question 13

Interference

Answer 13

interference is a phenomenon in which two coherent waves are combined by adding their intensities or displacements with due consideration for their phase difference

Question 13

Standing Wave

Answer 13

is a wave that oscillates in time but whose peak amplitude profile does not move in space

Question 13

Resonance

Answer 13

a phenomenon that occurs when an object or system is subjected to an external force or vibration that matches its natural frequency

Question 13

Eardrum

Answer 13

a thin, circular layer of tissue that separates your outer ear from your middle ear.

Question 13

Cochlea

Answer 13

a fluid-filled, spiral-shaped cavity found in the inner ear that plays a vital role in the sense of hearing and participates in the process of auditory transduction

Question 14

Intensity

Answer 14

the magnitude of a quantity per unit area

Question 15

Decibel

Answer 15

s a relative unit of measurement equal to one tenth of a bel. It expresses the ratio of two values of a power or root-power quantity on a logarithmic scale

Question 15

Loudness

Answer 15

loudness is the subjective perception of sound pressure

Question 15

Doppler effect

Answer 15

the change in the frequency of a wave in relation to an observer who is moving relative to the source of the wave.

Question 16

Pitch

Answer 16

the quality of a sound governed by the rate of vibrations producing it; the degree of highness or lowness of a tone.

Question 16

Overtone

Answer 16

tone sounding above the fundamental tone when a string or air column vibrates as a whole, producing the fundamental, or first harmonic

Question 16

Ultrasonic

Answer 16

vibrations of frequencies greater than the upper limit of the audible range for humans

Question 17

Echolocation

Answer 17

the use of sound waves to determine the location of objects

Question 18

Acoustics

Answer 18

a branch of physics that deals with the study of mechanical waves in gases, liquids

Question 19

Sonar

Answer 19

Sound Navigation And Ranging,
